ROLL-PAPER HOLDER AND CUTTER.

$PECIFIGATION forming part of Letters Patent No; 452,720, dated May 19,1891.

Application filed september 20, 1888. Serial No. 285.873. (No model.)

To all whom it may concern.-

Be it known that I, ABBOTT Q. Ross, of Cincinnati, in the county ofHamilton and State of Ohio, haveinvented certain new and usefulImprovements in Paper-Roll Holders and Cutters; and I do hereby declarethe following to be a full, clear, and exact description of the same,reference being had to the accompanying drawings, forming a part of thisspecification, and to the letters of reference marked thereon.

In that class of paper-roll holders in which the roll of paper ismounted upon a concentric shaft or axis, and in which a knife orcuttingedge is provided, against which the free end of paper unwoundfrom the roll is drawn to sever a sheet, there is liability of racingthe roll when the end of paper is quickly pulled, thereby causing theunwinding of more paper than is needed or desired, and, furthermore,unlessthe roll is perfectly cylindrical, which seldom or never happens,it is apt to shift either forward or backward in'regaining itsequilibrium after a sheet has been removed,

thereby removing the new end of paper from a point convenient to begrasped and requiring the turning of the roll more or less to find saidend.

It is the object of my invention to so mount the roll as to prevent boththe aforesaid racing and the shifting of the roll in regaining itsequilibrium.

The means which I have contrived in carrying out my invention Iwillfirst describe, and then point out particularly in the claims at theend of this specification.

In the accompanying drawings, Figure 1 represents an end view of apaperroll holder embodying my improvements; Fig. 2, a crosssectionalview of the same; Fig. 3, a top plan View; Fig. 4, a longitudinalsectional view; Fig. 5,a detail View of a friction-roller against whichthe roll bears when the free end of the paper is pulled. Fig. 6 is aview showing a modified form of supporting-bar.

Similar letters of reference in the several figures indicate the sameparts.

The letter A indicates a frame consisting of uprights secured to-asuitable base and having substantially horizontal portions or arms A, asshown.

B represents a roll of paper, and C a cutframe, being preferably madefiat on the under surface, so as to prevent it from turning when therollis revolved. It willbe observed that this bar or support E does notfill the aperture of the roll nor the aperture of the bushings, if theyare used, and that consequently the support which it affords the roll iseccentric to the center of rotation of the roll. In other words, by theuse of this bar the roll is hung from above its center, which producesincreased friction at the point of support that overcomes any racingtendency and also prevents the dropping of the roll either forward orbackward when slightly elliptical or out of true. The upper surface ofthe supportingbar may be rounded, as shown in Fig. 6, or may be angularor polygonallyshaped, as shown in Figs. 1 and 2. In either case thefriction between it and the aperture 'of the roll or the bushings in theroll, if they be used, will be much greater than if the roll weremounted on a concentric support, as will be readily understood.

To remove the paper from the roll mounted as described it is onlynecessary that its free end be pulled out to the required distance underthe knife-blade O and then drawn upward, so as to cause the knife tosever it. As the roll is rotated by the draft upon the paper it is drawntoward the knife,and as it diminishes in size its supporting-barE slidesupon the arms A A in the direction indicated by the dotted arrow in Fig.l. \Vhen thus drawn forward, the roll might be permitted to beardirectly against the frame-work; but I preferably interpose afriction-roller F, (see Figs. 2 and 5,) in order that its operation maybe smoother and to prevent the paper being torn.

Guide-flanges A are formed upon the arms A, so as to properly confinethe supportingbar in its place on said arms and prevent its working out,and to permit a free and independent movement of the ends of thesupporting-bar upon the arms A, so that the bar will accommodateitselfto rolls that are more or less conical in form, the extremities of thebar are made rounded or beveled, as shown at c in Fig. 3. By thisprovision considerable independent motion of the ends of the bar isallowed without causin sgthcm to bind against the guide-llanges A Lugsor shoulders A are provided at the outer extremities of the arm A forthe bur pose of preventing the supporting-bar from sliding off said armwhen the roll is rotated backward.

Having thus described my invention,what I claim as new is- 1. In apaper-roll holder, the combination, with a roll of paper having acentral aperture, of an angular bar passing through said aperture andconstituting an eccentric support for the said roll, and horizontalguideways in which the ends of the supporting-bar rest, substantially asdescribed.

2. In a paper-roll holder, the combination, with the frame having thesubstantially hori zontal arms and the guide-flanges and end lugs orstops thereon, of the roll of paper and the bar constituting aneccentric support for the roll, said bar having the undersides of itsends squared for bearing on the horizontal arms, substantially asdescrbed.

3. In a paper-roll, holder and cutter, the combination, with the framehaving" the substantially horizontal arms provided with gnidellanges, ofthe roll of paper, and the rollsupporting bar having the beveled ends,substantially as and for the purpose specified.

-11. In a paper-roll holder and cutter, the combination, with the framehaving the substantiall y horizontal arms, of theknife,the roll, the barfor supporting the roll eccentrieally and having a sliding motion on thearms of the frame, and the friction roller against which the roll bearsand rotates when the free end of paper is drawn upon, substantially asdescribed.

5. In combination with a roll-paper holder and cutter, a supporting-baror axle provided with an angular upper surface adapted to support theroll, and a flat under surface adapted to slide on horizontal guideways,as herein set forth.

6. In a roll-paper holder and cutter, the combination, with the framehaving substantially horizontal guideways, of a supportingbar having[lat bearing-surfaces on which it is adapted to slide in said gnideways,as herein set forth.
